Solutions
Baicells recommends that all customers currently running an earlier version of BCE-ODU-1.0.8 upgrade their product to the BaiCE_BM_2.5.26 firmware.
Configurations
CPE would need to be configured and running on BCE-ODU-1.0.8 firmware and older along with being accessible on the internal network or public network. If the Web interface is enabled it will allow users to exploit using the above method.
